 Paul,  getting bored so to occupy the time I am looking at the
 complications for adding a turbo to a P ported engine. Not wishing to
 blow the backside out of the engine, but a gentle 5 pound boost. How
 do I size a turbo for this to occurr?  There are plenty of Ford RX7
 turbos out there (Chinese)  for $300.  Not that simple, so what
 parameters are needed?

Use the biggest turbo you can find and use a blow off valve on the intake manifold
set to 5 psi boost. The big turbo will have an easier time of it with the 1800 degree F
Wankel exhaust temp. Also use a vent on the exhaust manifold with a 1.25 inch
diameter hole. Forget the waste gate. It will do nothing. Turbos work and spin  on exhaust mass flow
and not exhaust pressure.

The video show water vapor coming out of the blow off valve with the engine running
at full boost. You may or may not need a intercooler. With only 5 psi boost and silicone nitride
apex seals probably not. Silicon nitride apex seals are essential with any boost.
